WILLIAM WOOD, OF HARTFORD, CONNECTICUT.

BRICK-MACHINE.

Specification of Letters Patent No. 29,645, dated August 14, 1860.

To all whom it may concern:

Be it known that I, WILLIAM lVooD, of the city of Hartford, county ofHartford, and State of Connecticut, have invented new and usefulImprovements in the Mode of Constructing Brick-Making Machines; and I dohereby declare that the following is a correct description thereof,reference being had to the accompanying` drawing and to the letters ofreference marked thereon.

The nature of my invention consists in levers, to press down the pistonrod and plate to fill the molds, with arrangements to raise up the samewhen the mold is filled, also a self acting arrangement for forcing outthe brick mold when it is lled, &c.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

In the drawings, Figure l a front view of the machine; Fig. 2 a sideviewgfFig. 3 a plan view showing center rod for forcing out the mold;Fig. et a side view of the same.

I construct the frame, clay box, the grinding process, piston and pressplate, and other parts, in the customary manner.

I make the lever A with a cam shaped lower end, to press on the wheel inthe head of the piston rod H, to force down the same and the press plateto press the clay into the mold. The upper part of the lever eX- tendssuffciently high to be acted on by the arms C, in the main shaft D, whenrevolving, and carry the same forward till it d epresses the end toallow the arm to pass over.

The lever B, is for raising up the piston and plate after doing the dutyof pressing the clay into the mold. The lower end of the lever isattached to the piston rod H, by means of a slot and a series of pins inthe rod Gr, so arranged that the rod can be shifted to adjust andregulate the distance the press plate travels up and down. The

upper end of the lever B, is actuated by the arms C, in the same manneras the lever A, and receives the action, instantly, after leaving thelever A, causing the same to depress, and lift up the piston and plateas before Stated. The spring lever E, reaches up the same height as thelevers A and B, to receive the action of the revolving arms C after lnected to the central slide K, reaching back to the two friction pulleysI), and the slide K, has a cross head S-topress out the brick mold whenfilled, the whole actuated by the lever E. Near the top of the lever E,I make a joint and attach a stiff spring T, as a preventative to damage.If there should be an obstruction to the mold coming out, by a stone orotherwise, the extra force required will cause the spring to yield andthe arm will bend the lever and pass over till the cause of theobstruction is removed. The spring u is to bring back the lever E andattachments after they have discharged the mold.

I/Vhat I claim as my invention, and desire to secure by Letters Patent,isy l. The construction and arrangement of the spring lever E, forthrowing out the mold, attached to the rock shaft F, and, actuated bythe direct action of the arms C from the main shaft D, in the mannerdescribed.

2. The arrangement of the two levers A, and B, one for pressing down thepiston and plate for filling the mold, and the other to lift up the sameafter the mold is filled, in the manner as herein described, beingoperated by the direct action of the arms C, from the main shaft D, asspecified.

3. The adjusting arrangement of the slot, sliding ring and pins Gr,attached to the piston rod II, and lever B, to regulate the pressure ofthe piston and press plate, all in the manner and for the purpose as setforth.
